【摘要】：以给定载荷和转速的滑动轴承为对象,基于统一Reynolds方程法建立润滑分析模型,研究几种分布形式的表面织构对润滑性能的影响。数值计算结果显示:织构分布对轴承偏心率和最小厚度影响显著,合理的部分分布织构明显改善轴承的润滑性能;存在最佳织构深度使得不同分布的织构润滑效果最优;矩形凹槽、矩形凹坑、圆形凹坑的织构分布中,矩形凹槽润滑效果最好;沿圆周方向单列矩形凹槽的润滑效果优于多列矩形凹坑;表面织构在高速、轻载时改善润滑的效果明显。
[Abstract]:The lubrication analysis model of sliding bearings with given load and rotation speed was established based on the unified Reynolds equation method. The influence of surface texture of several distributed forms on lubrication performance was studied. The numerical results show that the distribution of texture has a significant effect on the eccentricity and minimum thickness of bearing, reasonable partial distribution texture can obviously improve the lubricating performance of bearing, and the optimum texture depth makes the lubrication effect of different distribution texture optimal. In the texture distribution of rectangular grooves, rectangular grooves, circular pits, rectangular grooves have the best lubricating effect; the lubricating effect of single-row rectangular grooves along the circumference is better than that of multi-row rectangular pits; the surface texture is at high speed. The effect of improving lubrication in light load is obvious.
